What this phase means
Phase 1: the first tests in people. The main question is safety and dose, not whether it cures the condition. Groups are small. Side effects are watched closely.
Phase labels are FDA/ICH categories applied to the registry Phase field. They are not a finding that this study succeeded.
What the registry says happens
If you join, the listed intervention(s) are Cabotegravir 200 mg/mL, CAB >=400 mg/mL, or CAB Formulation I. The registry lists allocation as randomized. This is an open-label, dose-escalation study to investigate the safety, tolerability and pharmacokinetics (PK) of single subcutaneous (SC) administration of long acting (LA) Cabotegravir (CAB) 200 milligrams per milliliter (mg/mL) with Recombinant Human Hyaluronidase PH20 (rHuPH20) (Part A), a single-dose or repeat-dose SC or intramuscular (IM) administration of LA CAB (greater than or equal to) \>=400 mg/mL (Part C), single-dose IM administration of LA CAB Formulation I (Part C Cohort C8) and LA CAB Formulation J (Part C Cohort C11), and a single-dose or repeat-dose IM administration of rilpivirine (RPV) (Part E).
They plan to enroll about 214 people at 3 sites. Taking part typically means taking a study drug (or dummy pill) plus check-ins.
